To determine potential of loading Doppler echocardiography (DECG) in detection early, subclinical dysfunction of left ventricular pump capacity in patients with ischemic heart disease. Systolic and diastolic functions of the left ventricle (LV) before and during transesophageal electrocardiostimulation (TEECS) were assessed in 65 patients (55 males and 10 females, mean age 47 +/- 1.3 years) with effort angina functional class I, II and III and 25 control patients. Initial LV systolic function did not differ from control values. In the course of TEECS, LV systolic function declined in accordance with severity of angina and stimulation frequency. Initial LV diastolic function was reduced only in patients with angina class II and III. These changes were more pronounced in the course of TEECS. Stress Doppler echocardiography is a reliable tool in detection of early, preclinical impairment of cardiac pump function in patients with ischemic heart disease.
